My Firefox freezes (does not crash) frequently on Ubuntu 12.04

Posted

Hi. Firefox was working fine on my Ubuntu 12.04 LTS, but just about 2 days ago it started freezing very frequently. As I write this, sometimes the browsers "stops", without saying anything, and then it puts what I've written. It freezes for about 6 or 7 seconds, which is very annoying.

It happens when I'm doing anything: scrolling, switching tabs, right clicking, etc.

I'm using the packaged version of Firefox (I didn't download it manually).

I have fx17 canonical package and fx15 Mozilla version installed on 64bit Ubuntu12.4 and am not noticing problems.

Try Firefox in Safe Mode see if that helps

I would also recommend you turn on telemetry, as that allows Firefox Developers to receive anonymised data of real world firefox usage, and helps with identifying and solving problems like hangs

Well,

I also had this problem, and disabling Firefox cache fixed the issue for me.
